A New Benchmark for Chinese AI Image Generation! Meituan Longcat-Image Hands-On: Generation + Editing in One Go, No Failures Even with Rare Characters

AI Image Generation Heralds the "Chinese-Native" Era, Longcat-Image Makes a Stunning Debut

While most AI image generation tools still rely on complex English prompts and repeated parameter tuning, Meituan's LongCat Team officially launched a new AI image generation capability at the end of November — the"generation + editing"integrated tool built on the Longcat-Image model, completely breaking the creative barriers for Chinese users. Whether it's the quick image needs of ordinary users or the precise creative implementation of professional creators, this model has redefined the user experience of AI image generation with its core advantages of "fast image output, authentic texture, and accurate Chinese understanding".

Three Core Highlights, Reconstructing the AI Creation Process 

1. Seamless Generation + Editing, Modify "On the Fly" with Natural Language

The most disruptive innovation of Longcat-Image is its integration of the complete workflow from "text-to-image" to "image editing". There's no need to switch tools or memorize complex command formats — you can complete the entire creative process from first draft to final version using daily spoken language:

• Efficient image generation with simple prompts: Even with concise descriptions like "a cat by the window on a rainy day, warm yellow desk lamp, stack of old books" allow the model to accurately capture the atmosphere, layout, and details, generating finished images with delicate lighting and professional composition;

• Comprehensive coverage of 15 types of editing tasks: Supports scenarios such as object addition/removal, style transfer, perspective transformation, portrait retouching, and text modification. It can even implement complex instructions like "turn the person into a brown bear while maintaining the same posture" or "zoom out to show more indoor scenes";

• Multi-round editing without losing texture: The modified image perfectly matches the original in terms of lighting and style, with no sense of stitching. Portrait editing can also accurately retain facial features.

2. The"Pinnacle" of Chinese Text Generation, No Failures Even with Rare Chinese Characters

Addressing the pain points of Chinese creation, Longcat-Image has undergone in-depth optimization, becoming an "essential tool" for scenarios such as Chinese style and traditional culture:

• Zero-error character rendering: Both Chinese and English text in scenarios like store plaques, poster headlines, and book covers can be accurately rendered. Tests show that complex layouts such as "悦享宠爱季"(Joyful Pet Care Season) and "山野露营派对" (Mountain Camping Party)can be perfectly presented;

• High coverage of rare Chinese characters: Variant characters and calligraphic fonts (regular script, running script) such as "犇犇骏马Benben Junma" (galloping horses) and "翙翙凤凰Huihui Fenghuang" (soaring phoenix) can be stably generated, meeting the needs of traditional cultural creation;

• Intelligent typesetting saves time: Automatically matches font styles to scenarios (e.g.calligraphy for ancient styles, sans-serif for tech themes) and randomly optimizes font size, color, and line spacing, eliminating the need for manual adjustments.

3. Lightweight Architecture + High Performance, Runs on Consumer-Grade Graphics Cards

Unlike large models that require high-end hardware support, Longcat-Image adopts a hybrid backbone structure of MM-DiT and Single-DiT, combined with a VLM conditional encoder, achieving efficient inference while ensuring image quality:

• Image output speed is far superior to similar tools, with complex scenes responding in just a few seconds;

• Supports running on consumer-grade graphics cards, allowing ordinary users to experience it without professional equipment;

• Ranks in the first tier in public evaluations, with realism and rationality comparable to professional photographic works.

Real-World Tested Cases: These Creative Scenarios Can Be Accurately Realized

To verify the model's capabilities, we tested more than 10 high-difficulty creative requirements, and the results were surprising:

Instant Experience

• Ordinary users: No need to learn Prompt skills; generate avatars, wallpapers, and travel pictures quickly with Chinese;

• Professional creators: Iterate on ideas efficiently, save post-production time with multi-round editing, and eliminate manual text addition with the text generation function;

• Business&Merchants: Quickly produce promotional posters and event materials, supporting batch generation with consistent styles.

The launch of Longcat-Image is essentially a "dimensionality reduction attack" for AI creative tools — it no longer requires users to adapt to the tool, but instead allows the tool to actively adapt to users' creative habits. In-depth understanding of Chinese semantics, seamless connection between generation and editing, and a lightweight and efficient experience have truly brought AI image generation into an era where "Available for everyone". If you're tired of complex parameter tuning and English Prompts, why not try this "Chinese-native" AI image generation powerhouse — it may redefine your creative efficiency!
